TDSB spokesman Ryan Bird told CP24 that all but one case at Glamorgan Junior Public School is limited to one wing of the building.
Because of this, he said the rest of the school is not considered epidemic and is kept open.
“At this point, 58 students have been asked by TPH to self-isolate as a precaution,” Bird said in a statement to CP24.
There have been 2,159 school-related COVID-19 cases in Ontario since the start of the school year, including 61 more that were reported on Friday.
There are currently no schools closed due to COVID-19 outbreaks.
